Office: please send Luis to complete the call. Homeowner will notify office if he is interested in 2 surge protectors which can be installed at the time of service. Arrived at the home and met with Home owner. You show me where the air handler is in the attic, and proceeded to do diagnostics. The air handler has high voltage, has high voltage going to both transformers, Air has 24 V outgoing from the transformer. At the communication block there is 24 V. No 24 V exiting air handler control board. I also found float switch miss wired, will rewire upon installation of new air handler control board. went outside to check voltages on the condenser boards, there is high voltage, power being supply, check fuse on control board seems to be functioning, checked inverter board and seen green diode lights blinking. These condenser control boards look in operational order but will determine when primary board is installed. 8/13/24: arrived at the home and proceeded to install the air handler c
